1 INTRODUCTION The menstrual cycle of a naturally menstruating woman is regulated by the production of key hormones, of which oestrogen is one. Serum oestrogen concentration is typically low during menses, and gradually increases during the late follicular phase (LF) to its peak just before ovulation, after which it decreases during the luteal phase, then increases once more to roughly half its peak, before decreasing again prior to the start of the next cycle (Mishell et al., 1971).
